When Charles Joseph Panckoucke took over publication of Diderot's Encyclopedie in 1768, he promised to correct the cursory treatment of geography for which the first seventeen volumes had been criticized, with emphasis on the discoveries of the last 25 years. He employed Samuel Engel, a Swiss geographer, to write a series of articles about the northern regions and Didier Robert de Vaugondy to prepare ten maps to illustrate them. Engel rejected the De la Fonte Northwest Passage discoveries and believed the most sensible route from the Atlantic to the Pacific was along the north coast of Siberia. These maps illustrate the discoveries and various cartographic theories concerning the Pacific Northwest, East Asia and the North Pacific Ocean and include some of the most interesting comparative cartography of the eighteenth century

This handsome sheet has two contrasting historical maps, one inset into the other. The inset map is based on a world map by Plancius issued in 1641, while the larger map is based on Visscher's map of 1612. Other than a recognizable Baja California, the maps are filled with the cartographic myths of the 17^th century. The northwest coast bulges too far to the west. Both maps feature the seven cities of Cibola gathered around a spurious lake in the American Southwest.

Nice impression on good, strong paper with wide margins. One faint damp stain in the lower left, just into the map at the scale of miles, still very good.
